Heat Activated Cooling Fan Controller Circuit Using LM393-LM358 & LM35 Temperature Sensor

Heat activated cooling fan controller ( Thermal Activated Cooling Fan Driver Circuit) is a simple project which operates a Brush-Less fan when the temperature in a particular area goes above a set point, when temperature return normal, fan automatically turns off. The project is built using LM358 Op-amp ( Use LM393 instead for good performance) ,  and LM35 temperature Sensor.
